> Webhdfs assumes that SPNEGO's {{AuthenticationException}} is always fatal.  The exception
is thrown if authentication truly fails due to bad credentials, _but_ it's also thrown when
the auth token expires after 10h.  The retry policies are short-circuited and the fs becomes
unusable which is unsuitable for long running processes/daemons.
